Title: Preparation of alkali metal chlorates
IPC: C25B1/26
Filed: 1954-06-18
Abstract: <PICT:0757761/III/1> In a process for producing alkali metal chlorates by electrolysis of a solution of the chloride, the chloride solution is circulated in the interelectrode space between an anode and a cathode at such a speed that the OH-ions formed at the cathode cannot on the average, reach the anode, and by allowing the electrolyzed solution to absorb the evolved chlorine to produce hypochlorite and thereafter allowing the hypochlorite solution obtained to rest for a time and at a temperature sufficient for it to be chemically transformed to chlorate, the transformation being effected in a reaction space outside the zone of electrolysis. Control of the migration of the OH-ions and the absorption of chlorine to form hypochlorite are effected by suitably correlating the speed of circulation of the chloride solution and the value of the electrolysis current.  As shown in the Figure, chloride solution passes from vat 15 through line 16 to a vessel 4 beneath the electrolysis zone formed between a cathode 1 and an anode 2, through the interelectrode space to pass via pipe 7 to a vessel 9 where the chemical transformation of hypochlorite to chlorate occurs thence to a tank 12 from which the chloride solution now containing chlorate is recirculated through pump 14 and line 13 to the supply vat 15. Product chlorate solution is withdrawn from line 20.  The electrolysis gases, other than chlorine, consisting almost entirely of hydrogen are removed through tube 6.  In a process for producing sodium chlorate, the cathodeanode assembly had a height of 16 cms. and an interelectrode distance of 2 cms. with a graphite anode 6 cms. in diameter.  Employing a current density of 10 amps per square decimeter, a minimum flow of electrolyte of 2.5 litres per hour was theoretically necessary to obtain the desired effect but to avoid disturbances due to gas evolution a flow of 10 litres per hour was employed.  The hypochlorite solution at a pH of 8 passed from the electrolysis zone to the vessel 9 where the temperature was maintained at 60 DEG C. by heating means 10 and the pH reduced to 7.2 by acidification with hydrochloric acid.  The solution after the transformation in vat 9 had a pH of 6.5.  If desired the vat 9, instead of being separate from the electrolysis zone as shown may be adjacent to but distinct from the electrolysis zone proper.  It is preferred to recycle the chloride solution containing the formed hypochlorite around the cycle until the chlorate concentration is sufficiently high or alternatively several plants may be arranged in series such that the pump 14 of one delivers the chloride/chlorate solution to the vat 15 of the next one.  Fresh chloride solution is introduced into the system at a point 19.  Specification 714,234 is referred to.

Abstract: 1,191,781. Controlling helicopters. UNITED AIRCRACT CORP. 17 April, 1968 [2 May, 1967], No. 18057/68. Headings B7G and B7W. A helicopter 10 has a lift rotor 16 anti-torque rotor 36 that may be pivoted to provide forward propulsion, and wings 20 mounted on the fuselage for pitch-changing movement about axis 22 under control of a jack 24. The rotor and pitch-changing mechanism is conventional with a swashplate 68, 70 of which the lower element is tiltable by actuators 80, 86, 88. The actuator 80 corresponding to the 270 degrees position of the rotor blades has a hollow piston rod 90 within which is fixed at 98 a rod 94 formed at its other extremity with a slug 92 positioned within coils 96 to function as a transducer when excessive vibratory control loads are experienced in the rotor blades at the 270 degrees position when the rotor commences to stall. The signal from the transducer is filtered to remove the steady-state control component of the signal and the resulting vibratory signal is rectified and amplified to energize actuator 24 to increase the incidence and lift of wings 20, thereby reducing the loading and tendency to stall of the rotor 16. Instead of a transducer a strain gauge may be incorporated in either of the swashplate elements and the control signal may control other forms of lift-increasing or forward-thrust increasing devices.

Title: Improvements in or relating to alarm devices for indicating failure of the paper feed mechanism in teleprinters
IPC: H04L13/06
Filed: 1945-07-19
Abstract: 596,112. Tape teleprinters. CREED & CO., Ltd., and SALMON, R. D. July 19, 1945, No. 18527. Addition to 582,528. [Class 100 (iv)] In the tape teleprinter described in the parent Specification wherein mechanical,means are provided to operate an alarm in the event of the feeding rollers failing to grip the tape or should the tape break, the devices are modified so that the alarm is operated should the tape become jambed either in the supply roll or between the feed-roll and the platen. Operation of the alarm also occurs if the frame carrying the paper-feeding, and ink-ribbon feeding mechanisms is not in operative position. For these purposes, the latch 48 has a detent 78 normally engaging the alarm-operating lever 80 to prevent operation of the alarm, and has a hole 79 through which the trip-arm 42 passes if the tape-feed operates normally. Should the tape become jambed, operation of the feedrollers will shorten the loop of tape passing around the roller 17 thus moving the arm 42 so that it engages the latch 48 on one side of the hole 79 and releases the lever 80 to close alarm contacts 53. The latch 48 is mounted on the frame carrying the paper &c. feeding mechanisms, and the lever 80 is mounted on a fixed part of the machine, so that when the frame is in an inoperative position, the detent 78 is moved away from the lever 80 thus permitting the alarm contacts to close.

Title: Improvements in or relating to picture projection theatres
IPC: G03B21/00
Filed: 1964-05-05
Abstract: 1,041,515. Optical projection apparatus. W. H. RAMSELL. May 5, 1964 [May 13, 1963], No. 18596/64. Heading G2J. [Also in Division E1] A dual projection theatre provides two facing groups of seats 40, 41, each within the optimum viewing zone of an associated, elevated, rear projection screen 21, 20, and comprises a dual beam projector 46 in compartment 45 whose beams 60, 61 are reflected on to the screens by mirrors 62, 63, and 64, 65, the beams passing through tunnels 30a and 30b above the ceiling 12 and into screen compartments 31, 32. Normal or wide screens may be used with cine or still projection. The projector unit has twin projectors 75, 76 directing beams into console 70 each beam being reflected first upwardly and then back parallel to beams 80, 92 on to reflectors 85, 97 which then direct the beams to a pivoting beam selector mirror 87. The beam from selector 87 passes through half-silvered mirror 89 to provide one projection beam 60, while the transmitted beam 90 is reflected at mirror 91 to provide beam 61. The selector 87 is controlled by relay coil 101, while relays 103,104 operate masks or gates in front of the projectors 75, 76. In an alternative form projectors 75, 76 produce beams at parallel light which are focused on the screens by relay controlled turret lenses mounted in the exit apertures 72, 73 of the console. By this means, reflectors of the same size may be used with the non-divergent beams and space is economised. In a further alternative, reflection in a vertical plane is carried out after the beam selector stage, but before beam-splitting.

Title: Improvements in or relating to record controlled statistical machines
Filed: 1935-06-28
Abstract: 458,806. Statistical machines. HUTCHINGS, F. W., 14, Rue Clairaut, Paris. June 28, 1935, No. 18610. [Class 106 (i)] A removable connection box for location between the card-sensing pin box and the stop basket comprises a frame 1, 2 carrying columns of transmission elements 4 and means 6, 10, 11, 3 for each such column which is actuated by a sensing pin to displace the elements along the column when that pin reads a card hole, these transmission elements 4 being so arranged that a given element is always actuated by the same sensing pin in all positions of the transmission elements but actuates a different stop A in the stop basket according to the position to which the column of transmission elements 4 as a whole has been displaced. The Fig. shows mechanism for one card column. The five sensing pins of the half, or sectionalized, card column raise extension wires 5, 6. A slide 3 for each column carries the four transmission elements 4 and moves along the direction of the column in slotted side pieces 2 of the frame. The member 10 is constrained to move vertically by slot 14 and guide 15 and, when raised by the extension wire 6, a pin 11 on it meets a cam face 12 on slide 3 and forces the latter to the right. Each extension wire 5 coacts always with the broadened end 8 of its respective element 4 where the slide 3 is in its left-hand or right-hand position, but each element 4 will lift one or other of two stops A in the stop basket according to the position of the slide 3. According, therefore, as to whether a card hole in a sectionalized column causing the lifting of a wire 5 is accompanied or not by a hole which causes the lifting of wire 6, the five hole-positions of a half, or sectionalized, card column may control nine stops A, 17. If wire 6 alone be raised the member 10 raises a nought shutter release bar 17 so that the nought shutter for the column is withdrawn and the adding sector is allowed to come forward to the fixed " 9 " stop. The entire connection box may be readily removed and replaced by a normal box, since it has guides coacting with similar guides on the tabulator and locking means for holding it in correct position, similar to known guiding and locking means. Specification 396,806 is referred to. The invention is applicable to a machine controlled by a perforated strip instead of perforated cards.

Patent GB-146865-A (GB)
Title: Process for purifying glycerine
IPC: C11D19/00
Filed: 1920-07-05
Abstract: Electric treatment is employed, with the aid of electro-osmotic diaphragms, which prevent the migration of glycerine itself.  The crude glycerine, either dilute or concentrated, may be placed in the cathode compartment of a cell having an electro-positive diaphragm, to remove acid residues, or in the anode compartment of a cell having an electro-negative diaphragm, to remove bases, when, however, some decomposition of the glycerine occurs.  Another method consists in separating the crude liquid from both electrodes.  If both diaphragms are of electro-negative material, such as parchment paper, viscose, or hemp fabric, all the basic constituents, and a part of the colloidal impurities, such as colouring-matter, migrate towards the cathode.  Some of the electro-negative substances pass into the anode compartment, but many organic acids and a part of the colouring-matter cannot pass the diaphragm.  Certain other impurities are precipitated in the middle compartment.  If both diaphragms are of electro-positive materials, such as animal membranes or leather, all the acid constituents and the inorganic bases are removed.  In cases where neither of the last two processes is sufficient, the glycerine may be subjected to both treatments in succession, or a single treatment between one electro-positive and one electronegative or indifferent diaphragm may suffice.  Diaphragms of mineral matter may be used in stead of organic materials.  Heat promotes the purifying process.  Before electro-osmotic treatment, the liquid may be partially purified by known methods, for instance with barium carbonate and sulphuric or oxalic acid.  This operation may be effected in the electrolytic cell.  Colloidal or absorptive materials may also be added to accelerate the electric treatment and assist in separating the pigments.  The purified glycerine obtained may be distilled, or employed without further treatment.  The process is applicable to crude glycerine obtained by Twitchell hydrolysis, by autoclave hydrolysis, from soap lyes, by fermentation, or synthetically.
